Every Email.
Checked. Scored.
Perfect.
Presend is a gate, not an assistant. It stands in the compose window and stops the sends you'd regret — leaked secrets, wrong recipients, AI-slop, off-voice tone — then rewrites in your voice. Add any check you want in plain English. Rules run locally.
Trusted by professionals at
ShopifyShopifyEverything your email
should have had.
A send-time gate: local checks, a hard send-guard, voice-preserving rewrites, and any check you write yourself — all in one extension.
Pre-Send Safety Net
Local rules catch leaked secrets & PII, wrong recipients, broken links, and AI-slop the moment before you hit send — zero AI cost, zero latency.
Send-Guard
Real risks don't just get flagged — the send is blocked until you confirm. A gate, not a warning banner you'll dismiss by day two.
Voice & Slop Scoring
AI scores your email 0-100 for authentic voice and AI-generated content, so you catch the drafts that read like a machine wrote them.
Voice-Preserving Rewrite
One click strips AI-slop while keeping your voice — More Me, Shorter, Less AI. Your email stops sounding like ChatGPT, not more like it.
Your Own Checks
Describe any check in plain English — 'don't let me sound passive-aggressive', 'always include a next step'. It runs at send time, only on your mail.
Custom Actions
Build multi-step check workflows with webhooks, conditions, MCP connectors, and AI prompts. Like GitHub Actions, but for email policy.
Local & Private
Layer-1 rules run in your browser. No Gmail API scopes means no restricted-scope OAuth and no annual security audit — and your text never leaves without your key.
Analytics Dashboard
Track check volume, rewrite rates, voice scores, and risky sends caught over time. All data persisted — no more restarting from zero.
Built for every email moment.

Each one is a reputation decision.
Presend doesn't just catch typos. It catches the email that leaks your client's data, the reply-all to 500 people, the draft that sounds like ChatGPT wrote it. Every. Single. Time.
Three steps.
Zero friction.
Install the Extension
Add Presend to Chrome in one click. It works silently inside Gmail and Outlook — no new app to learn.
Write Your Email
Compose as usual. Presend watches in the background and runs 10+ checks the moment you're about to send.
Review & Send Perfectly
See your voice score, slop score, and any findings. One-click rewrite to fix issues. Send with confidence.
Wall of Love
From leaked API keys to accidental reply-alls — hear how Presend saved their day.
“Presend caught a leaked API key in an email I was about to send to a client. That alone justified the install.”
Sarah Chen
Engineering Lead, Fintech Startup
“The voice scoring is wild. I type an email, it tells me 'this sounds 40% like AI slop' and I'm like... fair enough. The rewrite button actually fixes it.”
Marcus Rivera
VP Sales, SaaS Company
“I used to spend 5 minutes re-reading every important email. Now I just hit send and Presend catches everything before it goes out.”
Emily Watson
Account Executive, Enterprise
“I wrote a personal check in plain English — 'never let me send without a clear next step'. It's caught me a dozen times. Feels custom-built for how I write.”
David Kim
Product Manager, Tech Co
“We rolled it out to the whole sales team. The custom rules feature lets us enforce compliance — no PII in emails, mandatory disclaimers. Saves us from legal nightmares.”
James Liu
Director of Sales Ops
“It's not another AI assistant trying to write my emails. It just quietly stops the bad ones from going out. That's exactly what I wanted and nothing more.”
Aisha Patel
Founder & CEO
“The send-guard literally blocked me from firing off a reply with a client's private data in it. It made me confirm first. That one save paid for the year.”
Tom Bradley
Customer Success Lead
“I accidentally CC'd 'all@company' on a sensitive email once. Never again. Presend's external recipient warning has saved me at least 5 times already.”
